Instruct Image Processing Center

Electron Microscopy Image Processing
FlexibilityHub

The Instruct Image Processing Service provides state-of-the-art software infrastructure, support and image processing services for elucidating the structure of biological macromolecules by cryo-EM Single Particle Analysis and cellular subsections by cryo-Electron Tomography. This service is provided through Scipion, a software that allows the definition of image processing pipelines capable of analysing the raw data acquired by the microscope and turning it into insightful biological knowledge.

Equipment

The I2PC has an increasing set of servers and workstations devoted to the processing and storage of Cryo-EM project data. This hardware composes a system integrating the facility and the processing center. The main hardware is:

  • Machines for in-line, on-the-fly processing of microscope data (devoted to CryoEM-CSIC)
    • 1 server for “super-resolution” imaging: 112 cores, 4x NVIDIA A30 24GB GPU, 512GB RAM and 30TB storage
    • 2 servers for “regular” imaging: 80 cores, 4x NVIDIA T4 16GB GPU, 384GB RAM and 30TB storage
    • 1 workstation for FIB-SEM and correlative imaging: 104 cores, 4x NVIDIA 3090 24GB GPU, 512GB RAM and 80TB storage
  • Servers for SPA, Cryo-ET and Flexibility Analysis
    • 1 server for projects: 32 cores, 8x NVIDIA 1080Ti 12GB GPU, 256GB RAM and 20TB storage
    • 2 servers for projects: 80 cores, 4x NVIDIA T4 16GB GPU, 384GB RAM and 30TB storage
  • Servers for storage
    • 4 storage servers (500TB/500TB/80TB/50TB, respectively) for data retrieval and mid-term storage
    • Tape system (30TB/tape) for very long term storage

    3DBioNotes

    The COVID-19 3DBionotes platform has been created and hosted by the Instruct Image Processing Centre, in the Biocomputing Unit of the National Centre of Biotechnology in Spain (CNB-CSIC), in close collaboration with ELIXIR-ES. Data has been acquired from a wide range of sources, including cryo-EM, as well as X-Ray crystallography and NMR.

    A novel set of annotations for this COVID-19 edition includes functional mapping of the residues that likely constitute ligand and protein-protein interaction binding sites, drug screening, validation and quality measurements, as well as model refinements provided by the Coronavirus Structural Taskforce. This has been a crucial resource for structural biology researchers throughout the COVID-19 pandemic, providing easy access to regularly updated data on the structure of the virus (link to webpage).
